6 Ways to Force Quit Mac Applications

Do you need to quit an unresponsive Mac OS X app? Is your Mac seeing the infamously dreaded spinning beachball of death? Is an app failing to respond to any input? Maybe you have an errant process or two? When any of the above happens, you’ll probably want to force quit the application in question, and that’s what we’ll cover with six different ways to force quit apps on a Mac.

Whatever your skill level with Mac OS X, you’ll find a way to forcibly exit out of an app. Take a moment to remember a few keyboard shortcuts or sequences now and save yourself a hassle later when Mac apps start acting up.

1) Force Quit Currently Active Mac App with the Keyboard

Hold down Command+Option+Shift+Escape for a second or two until the app forcibly closes. This is the quickest way to force quit the foreground application in Mac OS X and a very good keyboard shortcut to remember.

2) Bring Up the “Force Quit Applications” Window in OS X

Hit Command+Option+Escape to bring up the simple “Force Quit Applications” window, then click to select the app name, followed by clicking the “Force Quit” button to end the app immediately. Think of this as a simplified version of Activity Monitor, and it’s also a great keystroke to remember to use since it allows for quickly ceasing multiple apps.

3) Force Quitting Apps from the Dock

Option + Right Click on an apps icon in the Dock to bring up the “Force Quit” option, selecting this will kill the app without any confirmation.

4) Force Quit from the Apple Menu

Hold the Shift Key and click on the  Apple menu to find “Force Quit [Application Name]”. This is easy to remember but not necessarily the most powerful method, since sometimes an application is completely unresponsive and the menus are inaccessible.

5) Use Activity Monitor to Force Quit Apps

Bring up Spotlight with Command+Space and then type Activity Monitor. Select the process name or ID you wish to kill (unresponsive apps will usually appear as red), and hit the red “Quit Process” button. Think of this as the Mac equivalent to a task manager from the Windows world and a more complex version of the second tips Force Quit window. If one of the previous methods fails, this will almost certainly work.

6) Using the Terminal & kill Command

If all else fails, using the command line is a surefire way to force an app or process to quit by issuing the low-level kill command. Launch the Terminal and type one of the following commands:

killall [processname]

For example, “killall Safari” would kill all instances of the Safari process. If you know the process id, which you can find with the ps or ‘ps aux’ command. Aim kill at that process specifically:

kill -9 [pid]

The kill commands will take out just about anything, and sometimes have the side effect of not honoring Versions, Window Restore, and Auto-Save, so be cautious of potential data loss.

Bonus: Force Quit on iOS

OK it’s not quite the Mac, but it’s useful to know for mobile users: from the iOS side of things, you can force quit apps on iPhone, iPad, or iPod touch, by holding down the Power button until the slide to power option appears, and then hold the Home button until the app closes.

    kill like a boss:
    # Kill Like a Boss
    Killall() {
    QSTRING=$*
    PROC=`ps aux | grep -i ${QSTRING} | grep -v grep | awk ‘{print $2}’`
    if [ ! -n “$PROC” ]; then
    echo “0 PID found with the matching String: \”${QSTRING}\”.”
    else
    NUMPROC=`echo $PROC | awk ‘{print NF}’`
    echo “Found $NUMPROC PIDs with the matching String: \”${QSTRING}\”.”
    sudo kill -9 $PROC
    echo “All process Killed.”
    fi
    }

    Had NO idea about the first one (adding shift to command-option-escape): NICE or the last one (killing apps on iOS). Thankfully, I have had very few problems with stuck apps on iOS.

    Finally! I finally got rid of it thanks to you and Activity Monitor. I just wonder why none of the other sites I searched suggested Activity Monitor as a way of disposing of files that you couldn’t get to go away any other way. Thanks again.
